n.鼠穴；狭窄的出口

Mouse hole wouldn't line up. Rat hole! 小鼠洞不正,不能用,请用大鼠洞接单根!

Lower the drillpipe joint into the mouse hole, and remove air tugger and lifting cap. 下放单根进小鼠洞，摘掉气动绞车和提丝。

The Floormen dope the box and install the lifting cap, attach the air tugger and lift the joint clear of the mouse hole. 钻工给母扣抹上丝扣油，带上护丝，挂上气动绞车把单根提离小鼠洞。

If the rig is equipped with a top drive, the Driller activates the linktilt towards the joint in the mouse hole and the Floormen latch the elevators. 如果钻机配备了顶驱，司钻打前伸按钮使吊卡靠近小鼠洞中的单根，钻工扣上吊卡。

If a top drive is used, after the single has been broken out, the Driller uses the linktilt to move the single towards and into the mouse hole. 如果配备了顶驱，卸开扣后，司钻打前伸按钮，并把单根推向、放入小鼠洞。
